ABSTRACT

A solution for automated food selection includes: an order processing component operable to receive an order identifying an item; a selection component comprising: a first hyperspectral sensor operable to sense a reflection from the item and produce a sensor output based at least on the reflection; and a picking mechanism; a control component operable to: based at least on identification of the item, select a hyperspectral profile from a set of hyperspectral profiles; compare the sensor output with the selected hyperspectral profile; and based at least on the comparison, determine whether to select the item for fulfillment of the order, wherein the picking mechanism is operable to divert the item to a selection output based at least on a determination to select the item for fulfillment of the order; and a transport component operable to transport the item to an order storage zone.

BACKGROUND

Selecting perishable food items, such as produce, for customer order fulfillment typically requires human labor. This is because, even if the perishable food items had passed inspection upon arrival at the order-fulfilling facility (such as a retail facility that delivers or provides curbside pick-up), the condition of the perishable food items may change between arrival and ultimate delivery to a customer. Although the perishable food items may have been fresh or even in a pre-ripe state, multiple factors, including time and environmental conditions (temperature and humidity), may impact the rate of spoilage while stored in inventory locations or a staging location for customer pick-up. Humans that are trained to properly ascertain the state of perishable food items are thus used to pick specific ones of the perishable food items for order fulfillment. Any limitations on the human workforce, such as training, illness, and other scheduling issues may then negatively impact order fulfillment capacity.

Aspects of the disclosure operate in an unconventional way to sense a hyperspectral a reflection from an item (e.g., a perishable food item), compare sensor output with a selected hyperspectral profile, and determining whether to select the item for fulfillment of an order. For example, a solution for automated food selection includes: an order processing component operable to receive an order identifying an item; a selection component comprising: a first hyperspectral sensor operable to sense a reflection from the item and produce a sensor output based at least on the reflection; and a picking mechanism; a control component operable to: receive the order from the order processing component; receive the sensor output from the selection component; based at least on identification of the item, select a hyperspectral profile from a set of hyperspectral profiles; compare the sensor output with the selected hyperspectral profile; and based at least on the comparison, determine whether to select the item for fulfillment of the order, wherein the picking mechanism is operable to divert the item to a selection output based at least on a determination to select the item for fulfillment of the order; and a transport component operable to transport the item to an order storage zone.

Aspects of the disclosure provide a technical solution that improves operational efficiency by permitting automated picking of perishable food items (e.g., produce items such as fruits and vegetables). This permits automating (at least partially) order fulfillment centers for higher operational volumes.

FIG. 1 illustrates an exemplary arrangement 100 that advantageously uses hyperspectral sensing in automated food selection (e.g., selection of perishable food items for automated order fulfillment). For example, arrangement 100 permits a customer 102 to place an order 104 for an item 120 (e.g., a perishable food item) over a network 830, and then pick up (retrieve) a suitably selected item 120 s (selected version of item 120) from an order storage zone 500, which may be an automated storage and retrieval system (ASRS) 500 a (described in relation to FIG. 5 ).

Components of arrangement 100 are described individually in relation to each of FIGS. 1-5 , and the interactions among the individual components are described in further detail following the description of FIG. 5 . Arrangement 100 includes an order processing component 110, which receives an order 104 from a customer 102 over a network 830. In some examples, order processing component 110 is implemented on a computing node 800 or a cloud resource 828. Network 830, computing node 800, and cloud resource 828 are described in further detail in relation to FIG. 8 .

Order 104 may include an item identification 106 that specifies item 120 (e.g., banana, apple, strawberry, etc.) and a quantity value 108 that specifies the count of items 120 desired. Order 104 may also include preferences such as a ripeness specification (e.g., rime now or ripe in two days), and a time estimate 114 of when customer 102 expects to retrieve item 120. In some examples, if hyperspectral sensing permits an estimate of how long item 120 has remaining prior to perishing, time estimate 114 may be used to select or reject a candidate item 120. At a later time, after retrieving item 120 s from order storage zone 500, customer 102 may provide customer feedback 116, identifying whether item 120 met expectations or had already perished. In some examples, customer feedback 116 may be used to update selection criteria for arrangement 100.

Order processing component 110 forwards order 104 to a control component 250, which may also be implemented as a computing node 800 or a cloud resource 828. Control component 250 also receives sensor output 206, which includes hyperspectral sensing of item 120, and uses a selection logic 260 to determine whether to select item 120 to fulfil order 104, or to reject item 120. Control component 250 leverages a data store 270 to support selection logic 260. Control component 250 is described in further detail in relation to FIG. 2B, and data store 270 is described in further detail in relation to FIG. 2C.

The action of selecting item 120 for order 104 or rejecting (not selecting) item 120 is performed by a selection component 200. Item 120 is transported among selection component 200, an inventory zone 118, which holds inventory of items 120 and other items that may be processed for selection or rejection by selection component 200, order storage zone 500, and a disposal zone 130. Transportation is provided by a transport component 400, which is illustrated in FIG. 4 , and includes a transport vehicle 122 a, a transport vehicle 122 b, and a transport vehicle 122 c. In some examples, inventory zone 118, selection component 200, order storage zone 500, and disposal zone 130 are in fixed locations, and transport vehicles 122 a-122 c move item 120. In some examples, one or more of inventory zone 118, selection component 200, order storage zone 500, and disposal zone 130 are immediately adjacent, so item 120 is moved via robot arms or conveyor belts rather than vehicles. In some examples, one or more of inventory zone 118, selection component 200, order storage zone 500, and disposal zone 130 is mobile and when item 120 is moved, it is moved within a mobile one of inventory zone 118, selection component 200, order storage zone 500, or disposal zone 130.

In some examples, item 120 is moved in container 124 a, container 124 b, or container 124 c. For example, container 124 a may be an inventory tote, used for ferrying inventory to and from shelves in inventory zone 118. Container 124 b may be a customer order tote, used for ferrying item 120 to order storage zone 500. Container 124 c may be a disposal tote, used for ferrying potentially spoiled produce to disposal zone 130.

In some examples, selection component 200 includes a plurality of selection stations, for example, selection station 202, selection station 202 a, selection station 202 b, and selection station 202 c. As illustrated, selection station 202 includes a hyperspectral sensor 204 (which provides at least a portion of sensor output 206), a picking mechanism 220. Picking mechanism 220 moves (diverts) item 120 to one of a selection output 230, a disposal output 232, and an inventory return output 234. If item 120 is diverted to selection output 230, item 120 will be transported to order storage zone 500. If item 120 is diverted to disposal output 232, item 120 will be transported to disposal zone 130. If item 120 is diverted to inventory return output 234, item 120 will be transported back to inventory zone 118. In some examples, selection stations 202 a are similarly equipped. Selection component 200 is described in further detail in relation to FIG. 2A.

A human inspector 132, or a more finely-trained automatic inspection solution, performs a detailed inspection of item 120 d, which is a version of item 120 that has been sent to disposal zone 130. Human inspector 132 makes a disposition determination for item 120 d, such as donate, offer for reduced price, or throw into the trash. Human inspector 132 also provides feedback using terminal 134, for example whether the determination made by control component 250 was correct. Control component 250 is then able to use this feedback to improve the quality of future determinations regarding ripeness and suitability for sale of perishable food items.

FIG. 2A shows further detail for selection component 200. Selection station 202, of selection component 200. As illustrated, selection station 202 includes two hyperspectral sensors 204 and 204 a, although, in some examples, a different number are used. Hyperspectral sensors 204 and 204 a provide at least a portion of sensor output 206. An optical camera 208 also provides a portion of sensor output 206. Some examples use a light source 210 that provides a calibrated spectrum so that a reflection 212 from item 120 has the proper spectral properties in order to make a proper determination of whether to select item 120. That is, in some examples, light source 210 and hyperspectral sensor 204 are calibrated (one or the other, or both) to produce a predetermined sensor output for a calibration standard. In this way, sensor output 206 will have the proper spectral properties when compared with known ripeness conditions. Hyperspectral sensor 204 a and optical camera 208 may be similarly calibrated with light source 210 or another light source.

In some examples, a barcode 214 accompanies item 120, either affixed to item 120 or a container holding item 120. A barcode reader 216 reads barcode 214 to identify item 120. The data read from barcode 214 may be added to sensor output 206 for forwarding to control component 250. Picking mechanism 220 moves item 120 to one of selection output 230, disposal output 232, and inventory return output 234, and may place item 120 into one of containers 124 a, 124 b, or 124 c. In some examples, a human operator 222 actually performs the picking, receiving instructions from control component 250 over a terminal 224.

FIG. 2B shows further detail for control component 250. Control component 250 has a profile selection component 252 that selects a hyperspectral profile to be selected hyperspectral profile 254, which is used for making the determination of whether to select item 120 to fulfil order 104. Further detail on hyperspectral profiles is provided in relation to FIG. 3 . Selected hyperspectral profile 254 is chosen (selected) based on information within order 104, for example item type (apple, banana, strawberry, or other) and ripeness preference which is indicated in customer preferences 256. Selection logic 260 uses selected hyperspectral profile 254 along with sensor output 206 to make the determination. Control component 250 may also have a profile update component 262 that uses feedback 264 to improve predetermined hyperspectral profiles stored in a set of hyperspectral profiles 274 (shown in FIG. 2C). Any of profile selection component 252, selection logic 260, and profile update component 262 may use or include at least a portion of a machine learning (ML) component 266. As used herein ML includes both ML and artificial intelligence (AI).

FIG. 2C shows further detail for data store 270. Data store 270 includes set of hyperspectral profiles 274 that may be indexed based on item type, supplier, sensed conditions (see FIG. 3 ) and ripeness estimates. In some examples, ripeness estimates include not yet ripe, ripe, and expired (perished). In some examples, ripeness estimates include the number of days until expiration. As illustrated, data store 270 also includes customer data 276, which includes order 104, a customer profile 278, and customer feedback 116. In some examples, customer profile 278 includes order histories and customer preferences that indicate whether the customer has a preference for items from a specific supplier or the average delay between placing an order an retrieving it (which may be used to set time estimate 114 of FIG. 1 ). In some examples, data store 270 also includes historical data 280 of prior item selections and feedback, industry data 282 including supplier information and food quality standards, and localization data 284 that may include the speed with which produce ripens and expires in the locality of arrangement 100. For example, certain perishable foods may expire in warmer climates during the summer than in colder climates during the winter.

FIG. 3 illustrates a notional hyperspectral plot 300 that forms the basis for hyperspectral selection criteria, in some examples of arrangement 100. Plot 300 shows intensity of reflection 212, against a vertical value axis 302, in various spectral bands, spread across a horizontal frequency axis 304. An optical range 306 is annotated on plot 300 to illustrate that sensed reflection 212 has hyperspectral frequency components outside of optical light frequencies. Five spectral components are illustrated, spectral component 310, spectral component 312, spectral component 314, spectral component 316, and spectral component 318, although it should be understood that a different number of spectral components (possibly hundreds or more) may be used. A lower threshold 320 and an upper threshold 322, which each varies by spectral band, are illustrated. In some examples, if each of spectral components 310-318 falls within lower threshold 320 and upper threshold 322, item 120 may be selected to fulfil order 104. In some examples, selection logic 260 uses more complex criteria, such as the value of one of spectral components 310-318 affects the range of acceptability (minimum and maximum value) for another one of spectral components 310-318.

FIG. 4A illustrates an option for implementing arrangement 100 using a stationary selection component 200. As illustrated in FIG. 4 a , each of inventory zone 118, selection component 200, order storage zone 500, and disposal zone 130 are in fixed locations. Transport component 400 includes transport vehicle 122 and transport vehicles 122 a-122 c. Transport vehicle 122 is shown as holding item 120 in a container 124, which may be one of containers 124 a-124 c of FIG. 1 , or a similar container. FIG. 4B illustrates another option for implementing arrangement 100 using a mobile selection component 200. In this illustrated option, selection station 202 moves around among inventory zone 118, order storage zone 500, and disposal zone 130, carrying item 120.

FIG. 5 illustrates ASRS 500 a, which may be an implementation of order storage zone 500. ASRS 500 a has a dispensing aperture 502, a user display screen 504, and a sensor 506, which may be a two-dimensional (2D) barcode reader. Item 120 s (e.g., item 120 after being selected for order 104) is contained within container 124 b in a storage location 510 (e.g., a shelf compartment) within ASRS 500 a.

To retrieve item 120, customer 102 brings customer's mobile device 520, showing a 2D barcode 522 to be read by sensor 506. Optionally, user display screen 504 is a touchscreen and customer 102 requests item 120 a via interaction with user display screen 504. ASRS 500 a repositions container 124 b to dispensing aperture 502, where customer 102 is able to pick it up. Note that FIG. 5 does not show ASRS 500 a and mobile device 520 at proper relative scale. ASRS 500 a is larger than mobile device 520, with a height and width on the order of multiple meters.

Thus, with reference to FIGS. 1-5 , arrangement 100 comprises order processing component 110 that is operable to receive order 104 identifying item 120. In some examples, item 120 comprises a perishable food item. In some examples, item 120 is identifiable (to selection component 200) by barcode 214. In some examples, order processing component 110 is further operable to identify a ripeness preference (e.g., from customer preferences 256 in order 104 and/or customer profile 278). Arrangement 100 further comprises selection component 200 comprising first hyperspectral sensor 204 that is operable to sense reflection 212 from item 120 and produce sensor output 206 based at least on reflection 212. Arrangement 100 further comprises picking mechanism 220, which is operable to divert item 120 to a selection output 230 based at least on a determination to select item 120 for fulfillment of order 104.

In some examples, selection component 200 further comprises light source 210 positioned to produce reflection 212 from item 120. In some examples, light source 210 and first hyperspectral sensor 204 are calibrated to produce a predetermined sensor output for a calibration standard. In some examples, selection component 200 further comprises at least one additional sensor operable to contribute additional sensor data to the sensor output. The additional sensor is selected from the list consisting of: second hyperspectral sensor 204 a positioned at a different viewing angle than first hyperspectral sensor 204 relative to item 120, and optical camera 208. The additional sensor(s) contribute additional sensor data to sensor output 206. In some examples, selection component 200 further comprises barcode reader 216, which is operable to identify item 120.

Picking mechanism 220 is further operable to divert item 120 to disposal output 232 based at least on a determination to not select item 120 for fulfillment of order 104, for example if control component 250 determines that item 120 may have passed its expiration. Picking mechanism 220 is further operable to divert item 120 to inventory return output 234, for example if control component 250 determines that item 120 has not yet passed its expiration (and thus is still viable), but it exceeds the quantity identified in quantity value 108 of order 104. In some examples, selection component 200 is stationary, and in some examples, selection component 200 is mobile. In some examples, selection component 200 comprises a plurality of selection stations (e.g., selection stations 202, 202 a, 202 b, and 202 c) and each selection station comprises a hyperspectral sensor (e.g., hyperspectral sensor 204). Arrangement 100 further comprises disposal zone 130.

Arrangement 100 further comprises control component 250, which is operable to receive order 104 from order processing component 110 and receive sensor output 206 from selection component 200. Control component 250 is also operable to, based at least on identification of item 120, select a hyperspectral profile (e.g., selected hyperspectral profile 254) from set of hyperspectral profiles 274. Control component 250 is also operable to compare sensor output 206 with selected hyperspectral profile 254 and, based at least on the comparison, determine whether to select item 120 for fulfillment of order 104. In some examples, control component 250 is further operable to select the hyperspectral profile based at least on a ripeness preference, which may be specified in order 104 and/or customer profile 278. In some examples, control component 250 is further operable to select the hyperspectral profile based at least on an expected storage duration in order storage zone 500, for example as indicated in time estimate 114. In some examples, control component 250 is co-located with selection component 200.

In some examples, hyperspectral profile update component 262 is operable to update set of hyperspectral profiles 274 based at least on received feedback 264 or environmental conditions (e.g., in historical data 280 and/or localization data 284). In some examples, received feedback 264 comprises customer feedback 116. In some examples, received feedback 264 comprises feedback from an inspection process at disposal zone 130. In some examples, hyperspectral profile update component 262 comprises ML component 266.

Arrangement 100 further comprises transport component 400, which is operable to transport item 120 to order storage zone 500. In some examples, transport component is further operable to transport item 120 to/from inventory zone 118 to selection component 200, to transport item 120 to/from disposal zone 130, and/or to/from order storage zone 500. Control component 250 is further operable to instruct transport component 400. In some examples, order storage zone 500 comprises an ASRS 500 a.

FIG. 6 shows a flow chart 600 of exemplary operations associated with arrangement 100 (of FIG. 1 ), for example, automated food selection using hyperspectral sensing. In some examples, some or all of the computer operations described for flow chart 600 are performed as computer-executable instructions on computing node 800 (see FIG. 8 ). Flow chart 600 commences with operation 602, which includes receiving order 104 identifying item 120. In some examples, item 120 comprises a perishable food item. Customer profile 278 is read during operation 604. Operation 606 includes identifying a ripeness preference, for example from order 104 and/or customer profile 278. Item 120 is retrieved from inventory zone 118 into selection component 200 during operation 608, for example by transporting item 120 from inventory zone 118 to selection component 200.

In some examples, item 120 is identified by barcode 214 in operation 610. Light source 210, which may be a calibrated light source, generates illumination in operation 612, thereby producing reflection 212 from item 120 with light source 210. Operation 614 includes sensing, by first hyperspectral sensor 204 of selection component 200, reflection 212 from item 120. Operation 616 includes producing, based at least on reflection 212, sensor output 206. In some examples, operation 616 further includes contributing additional sensor data to sensor output 206 by at least one additional sensor. The additional sensor is at least one of: second hyperspectral sensor 204 a positioned at a different viewing angle than first hyperspectral sensor 204 relative to item 120, and optical camera 208.

Operation 618 includes, based at least on identification of item 120, selecting a hyperspectral profile (e.g., selected hyperspectral profile 254) from set of hyperspectral profiles 274. In some examples, selecting the hyperspectral profile comprises selecting the hyperspectral profile based at least on the ripeness preference. In some examples the hyperspectral profile is selected based at least on an expected storage duration in order storage zone 500. Operation 620 includes comparing sensor output 206 with selected hyperspectral profile 254. In some examples, the result of this comparison returns an expected expiration date (when item 120 has perished, or is below a quality threshold). Operation 622 includes, based at least on the comparison, determining whether to select item 120 for fulfillment of order 104. Operation 624 includes control component 250 generating control instructions to send to selection component 200 (e.g., whether to select item 120, return item 120 to inventory zone 118, or send item 120 to disposal zone 130).

Selection component 200 receives the determination, regarding item 120, in operation 626, and implements the three-way option indicated at 628: select for order 104, return to inventory zone 118, or send to disposal zone 130. If the determination is selection of item 120, operation 630 includes, based at least on a determination to select item 120 for fulfillment of order 104, diverting item 120 to selection output 230. Transport component 400 is instructed (for example by control component 250 or by selection component 200) to transport item 120 to order storage zone 500. Operation 634 includes the action of transporting item 120 to order storage zone 500. In some examples, order storage zone 500 comprises ASRS 500 a.

While item 120 is within order storage zone 500, decision operation 363 monitors for a time-out condition, for example item 120 perishing. Such a prediction could be made using the expected expiration date was determined when sensor output 206 was compared with selected hyperspectral profile 254, in operation 620. Upon expiration, flow chart 600 moves to operation 662, described below. Otherwise, customer 102 picks up (retrieves) item 120 in operation 638. Optionally, customer 102 provides customer feedback 116 regarding whether item 120 was in the requested condition (e.g., ripe or pre-ripe), or whether item 120 had already expired. Customer feedback 116 is received in operation 640.

If the determination at 628 is to return item 120 to inventory zone 118, operation 650 includes, based at least on a determination to not select item 120 for fulfillment of order 104, diverting item 120 to inventory return output 234. Transport component 400 is instructed in operation 652, and operation 654 includes transporting item 120 from selection component 200 to inventory zone 118.

If the determination at 628 is to send item 120 to disposal zone for further inspection, operation 660 includes, based at least on a determination to not select item 120 for fulfillment of order 104, diverting item 120 to disposal output 232. Transport component 400 is instructed in operation 662, and operation 664 includes transporting item 120 from selection component 200 to disposal zone 130. An inspection process occurs at disposal zone 130 during operation 666, for example human inspector 132 determining whether item 120 (now designated item 120 d) is still viable or needs to be immediately disposed of (e.g., donated, offered for reduced price, or thrown into the trash). This determination is indicated to control component 250 via terminal 134 as disposal feedback. Operation 668 includes control component 250 receiving disposal feedback from disposal zone 130. Received feedback 264 includes whichever of disposal feedback and customer feedback 116 that is received by control component 250.

Environmental factors, such as heat and humidity (which may affect ripening and perishing timelines), are monitored in operation 670. Supplier histories are monitored in operation 672, for example which supplier provides produce that spoils more quickly or ripens later after delivery. Such information may be stored in historical data, industry data, and/or localization data 284. This data may be used for training ML component 266, in operation 674. Operation 674 may also include training ML component 266 to better predict ripening and expiration, based on comparison of sensor output 206 with selected hyperspectral profile 254 (e.g., during operation 620). Operation 676 includes updating set of hyperspectral profiles 274 based at least on received feedback 264 or environmental conditions. That is, the data used for training ML component 266 may also be used to update set of hyperspectral profiles 274.
